10 Many adults are paying greater attention to personal fitness. The ability to carry out regular
exercise at home would be a convenient option.
Design a piece of fitness apparatus for personal use that will:
• exercise the stomach, arms and legs from a seated position;
• use a limited floor space (max 2 m × 1 m)
• be easy to store.
To assist you in design work, anthropometric data is given in Fig. 8

11 School caretakers often have to inspect school buildings and grounds at night.
On occasions repairs and maintenance may need to be carried out.
Design a torch that will:
• be easy to carry;
• give two levels of light intensity;
• be stable when positioned on the floor;
• be easily adjustable to direct light to where it is required.

12 A chain of shops offers a range of films for hire in the form of videos and DVDs.
The latest film releases need to be promoted to encourage customers to hire them.
Design a floor standing unit that will:
• be made from thick card;
• display six DVDs and 6 videos of the latest films;
• be easily assembled.
The unit must include provision for an easily attachable cut-out of a life-size character from the
latest film release.
